Method and arrangement for naming pictures to be saved in a mobile station

ABSTRACT

The invention relates to recording pictures, produced by a mobile station, in the mobile station and to naming the recordable picture files. In order to name the picture files, among the data available in the mobile station, there is searched a given feature associated to the picture, and the searched feature is added in the name suggestion list containing picture file name suggestions in order to create said name suggestion list. The created name suggestion list is displayed in the user interface, where the picture file name can be edited.

The invention relates to the recording of pictures pictured by a mobilestation in said mobile station, and particularly to the naming ofpicture files individually.

The quantity of pictures saved in a mobile station increasescontinuously, because more and more mobile stations are provided with acamera. The cameras can be fixed, integrated elements of the mobilestation, or auxiliary accessories to be installed in the mobile station.In addition, the quality of the cameras is continuously improved, at thesame time as their size is reduced, which means that cameras andpictures become more and more common in mobile stations. Pictures can betaken at shorter and shorter intervals, even as short continuous cyclesof successive pictures, which further increases the amount of picturesto be saved. When the amount of pictures taken by mobile stations andpictures to be saved in mobile stations increases, picture managementbecomes more and more important.

The finding of a certain picture from among a large amount of picturestakes time and is cumbersome. Typically the picture files saved in thememory of a mobile station are named so that the file name includes apossible initial part expressing that the file in question is a picturefile, a successive consecutive number and a qualifier according to thepicture format. The pictures can be named for instance so that at thebeginning of each picture name, there is added the character string“image”, and after this character string there is added the numberindicated by the calculator and a qualifier, for example “.jpg”. In somedevices, the user may define the character string that constitutes thefirst part of the picture file name, so that the files are immediatelyidentified as picture files. However, the first part is the same for allpicture files to be saved, and the file names are distinguished only bysaid value indicated by the calculator. One of the problems of filenames identified by calculator values is that generally the length ofthe file names has a maximum value. When this maximum length is achievedby the highest possible calculator value, for instance when the maximumlength of the file name is 6 characters and the latest name is“image9.jpg”, the calculator is reset, and both the calculator and thefile numbers start running over from the beginning. If the picture filecalled “image0.jpg” that was created earlier still is saved in themobile station when the calculator is reset, the new file “image0.jpg”is written over the earlier one, and the data saved in the earlier fileis lost.

Another problem when using file names distinguished by calculator valuesis the fact that the files are difficult to manage. Typically allpicture files are saved in the same location, and they are mutuallydistinguished only by consecutive numbers. When searching for a certainpicture file, generally the only alternative is to go through thepicture files until the desired file is found. The loading of thepictures on the display takes time, which means that the going throughof picture files is generally very slow and frustrating work. In thedisplay browser, the picture files are typically displayed in the sameorder in which they were saved, i.e. in the numerical order, and withoutopening the files, it is impossible to obtain any information ofpictures that are possibly mutually associateed or of certain picturesthat are being searched. When the number of pictures to be processed isseveral hundreds, the management and processing of prior art picturefiles becomes impossible.

In most cases, picture files are searched on the basis of their names.Often the file name is the only text-form description of the picturecontained in the file, apart from picture files with meta data embeddedtherein. Thus it is important to give names to the picture files. Thelarger is the number of picture files to be processed, the moresignificant are the file names in regard to the processing, searchingand finding certain pictures, and in general with respect to all formsof picture management and use.

The objective of the invention is to produce a method and arrangementfor making the processing of mobile station picture files easier, fasterand simpler. Another objective of the invention is to individualize thepicture files, so that their names can be clearly distinguished betweeneach other. Yet another objective is to give descriptive names to mobilestation picture files. Yet another objective of the invention is to namemobile station picture files simply and easily.

The objectives are achieved so that by means of data existing oravailable in the mobile station, there are produced name suggestions forthe picture file, whereafter the name suggestions are compiled in a namesuggestion list and the list is displayed in the user interface, wherethe picture file name can be edited.

The invention is characterized by what is set forth in the independentclaims. Other embodiments of the invention are described in thedependent claims.

According to an embodiment for naming a mobile station picture file, inwhich picture file there is saved a picture produced by the mobilestation camera, among the data available in the mobile station, there islooked up a given feature associated with the picture, said feature isadded as a name suggestion in the name suggestion list containing namesuggestions for the picture file in order to create said name suggestionlist, and the created name suggestion list is displayed in the userinterface, where the picture file name can be edited. The picture takenby the mobile station camera is in the mobile station saved in a picturefile, and for naming said picture file, there is surveyed the dataalready existing in the mobile station; among the possible namesuggestions, priority is given, according to given priority rules, tothe best name suggestion to be suggested for the user and to be adoptedas the default name for the picture file in question. According to anembodiment of the invention, the name suggestion list created on thebasis of searched and found name suggestions is displayed to the user inthe user interface, where the picture file name suggestion can beedited. According to an embodiment, in the user interface, where thepicture file name can be edited, the picture file name is selected amongthe displayed name suggestions by pointing a given suggestion or severalsuggestions. According to another embodiment, in the user interfacewhere the picture file name can be edited, the picture file name iscreated by editing the picture file name suggestion. The user of theuser interface can edit the suggested file name, select the desired filename among the given suggestions, compile the file name to consist ofseveral suggestions, or edit the suggestions. The method of namingpictures taken by a mobile station according to this embodiment is easyfor the user, because in the method for naming picture files, there areutilized data and texts that already exist in the mobile station, andthe user need not recreate them manually. By means of the menu, the usermay only choose the desired option by pointing the selected item, andthere is no need to rewrite for instance text that was already writtenonce.

The invention can be applied in all available mobile stations. Theinvention essentially enhances picture processing, such as recording,searching, looking up, listing, organizing in indices or archives etc.,because the file names given according to embodiments of the inventiontypically describe the contents of the picture in question. Apart fromindividualizing the files, descriptive file names also enable theidentification and finding of given pictures without opening the files.In addition, the arrangement according to the invention enables theprocessing of picture files in the mobile station and also makes theprocessing easier, and it is not necessary to transfer the pictures toanother device, such as a microprocessor, in order to process thepicture files. As for mobile stations, the arrangement according to theinvention brings added value, new features and functions. In addition,the arrangement according to the invention can easily be extended tofuture communication devices that record video image. Likewise, alongwith the development of image recognition algorithms and devices, saccording to the invention there are obtained improved name suggestionsdue to the picture produced by the camera, and they describe the picturecontent better.

Advantageous embodiments of the invention are described in more detailbelow with reference to the appended drawings, where

FIG. 1 illustrates a method according to an embodiment of the inventionfor naming picture files,

FIG. 2 is a block diagram illustrating a mobile station according to anembodiment of the invention, and

FIG. 3 illustrates a method according to an embodiment of the inventionfor creating name suggestions.

In FIG. 1, step 101, a picture is taken by the mobile station camera.Generally the picture is in digital form, and the camera required fortaking said picture is integrated as a stationary element of the mobilestation. The camera can also be connected as an auxiliary device in themobile station, in which case embodiments of the invention can also berealized in existing mobile stations that originally were not providedwith cameras. Here a picture may also mean a so-called video clipcontaining a series of successive pictures or recorded moving image.Also moving image recorded by a video camera, both by one integrated inthe mobile station and an auxiliary device, can be saved and namedaccording to an embodiment of the invention. In this application, allapplicable picture forms are called pictures.

A picture taken by a mobile station is typically saved in the memory ofthe mobile station. In step 102 of FIG. 1, there is created a namesuggestion list containing picture file name suggestions according to anembodiment of the invention on the basis of such data already existingin the mobile station that according to certain criteria is associateedwith the picture taken in step 101. The name suggestion list is compiledso that in a given section or element of the mobile station, there issearched and found or produced a piece of information that was alreadywritten or saved in the memory of the device or otherwise already existsin the device. Applicable produced information is saved in the memoryand added in the name suggestion list containing picture file namesuggestions. Thus the name suggestion list is compiled of data alreadyexisting or available in the mobile station, and the name suggestionscan be associateed for instance to the picture, its content, datacontained therein, time or place or event of shooting, and so on. Bymeans of the name suggestions given in the name suggestion list andcreated on the basis of features looked up in the mobile station, it ispossible, in an easy and user-friendly way, to select a descriptive namefor the picture file to be saved, which name is associateed to thepicture contained in the picture file.

The created name suggestion list is displayed to the user in a userinterface according to an embodiment in step 103. From the namesuggestion list created according to an embodiment, there is chosen,according to certain priority rules, the name suggestion that is bestassociateed to the picture in question as the default name for thepicture file. If for instance the name suggestion list includes a wordthat describes the contents of a picture, it can be set as the picturefile default name that is suggested as the picture file name in the userinterface in step 103. The chosen picture file default name is asuggestion that the user can easily accept. According to an embodiment,the user may also edit the suggested default name, for instance bychanging it or by adding something thereto. Said editing operations canalso be realized in a user interface according to an embodiment, byselecting from the generated name suggestion list a new name suggestionthat replaces the earlier suggestion or is combined thereto. Forexample, the name suggestion list may include the time of the shooting,and from said time, at the end of the suggested default name for thepicture file, there can be added the date or a verbal feature edited asa name suggestion on the basis of the time, such as summer, fall,evening, morning and so on.

According to an embodiment of the invention, a name suggestion listgenerated on the basis of the information already existing in the mobilestation makes the naming of picture files easier and automatic. When theprocessing and saving of pictures is made easier, the mobile station isused more for image processing, and there is no need to first transferthe pictures to other devices in order to be able to manage them. Usersget more functions and features in their devices, which again makes themobile stations more versatile and meaningful to use.

The arrangement according to this embodiment for naming a picture filethat records a picture taken by a mobile station camera comprises meansfor looking up a given feature associateed to the picture among theinformation available in the mobile station, means for generating a namesuggestion according to said feature that was looked up, means foradding the generated name suggestion in the picture file name suggestionlist and thus for creating said name suggestion list, means fordisplaying the created name suggestion list in the user interface andmeans for editing the picture file in the user interface. According toan embodiment, the arrangement also comprises means for arranging theinformation that was looked up in the mobile station in order to createa name suggestion for the picture file in a priority order according tocertain priority rules, means for arranging the name suggestions so thatthe one with the highest priority is first in the name suggestion list,and means for setting the first name suggestion from the list as thedefault name for the picture file.

FIG. 2 is a block diagram illustrating essential elements of anembodiment of the invention; the illustration does not include forinstance transmission and reception branches for establishing a networkconnection, for transmitting data into a network and for receiving datafrom a network, which elements do not have an essential effect in theinvention, although they are essentially important for the mobilestation itself. In the embodiment of FIG. 2, the control unit 201 takescare of the operation of the device and of controlling the operations.The control unit 201 comprises a microprocessor, by means of which thedevice operations are checked, controlled and observed. The control unit201 is connected to all other functional sections and components of thedevice either directly or through their individual control units. Anarrangement according to an embodiment includes means for feeding thepicture file name suggestion, for looking up the fed picture file namesuggestion in the mobile station, for editing the picture file name inthe user interface and for choosing the picture file name from the namesuggestion list created in the user interface by pointing out a givenname suggestion or several name suggestions. The data input deviceillustrated in FIG. 2 is a keypad 202. Naturally the input device canalso or alternatively be for example a touch display, a displayrequiring pencil input, a section receiving sound input, a mouse or anyother corresponding device for feeding data in the device. The data ofFIG. 2 is displayed in the display unit 203 in a user interfaceaccording to an embodiment. In addition, the device includes a memoryunit 204 for storing data.

FIG. 2 illustrates, by way of example, such sections of the device thatcan be looked through In order to create a name suggestion listaccording to the invention. According to an embodiment, all devicesamong the means mentioned in connection with the embodiment 2 can besoftware means. The functions described in embodiments can be realizedby means of existing sections and components, so that they areprogrammed to function according to embodiments of the invention.According to an embodiment, the arrangement comprises means for findingthe mobile station date and time Information associated to the moment ofshooting, for generating name suggestions of the found information, andfor adding a name suggestion in the picture file name suggestion list.In the exemplary embodiment illustrated in FIG. 2, there is representeda clock 205 in which the time information of the moment of shooting islooked up. Typically the time information comprises a time and a date,which can be processed into numerical name suggestions or verbal namesuggestions for instance on the basis of the found name of the month,time of day or the season.

According to an embodiment, the arrangement comprises means for lookingup or searching from the mobile station a calendar event associated at agiven accuracy to the moment of shooting, and for adding the possiblyfound calendar event as a name suggestion in the picture file namesuggestion list. In FIG. 2, there is illustrated a calendar 206 that cancontain notes and reminders essentially associated to a given time thatcan at a given accuracy be compared with the moment of shooting.Typically the user feeds data in the calendar through the keypad 202.The data associated to the calendar 206 can be saved in the memory unitof the device, in a part of the memory that is allocated for thecalendar, or in a separate memory unit 206 of the calendar, which is notillustrated in FIG. 2. The arrangement also includes means for comparingthe time information of the shooting moment or the time informationbrought in the list from the clock with the time information of thefound calendar event.

According to an embodiment, the arrangement also comprises means forlooking up the previously saved picture file name in the mobile stationand for adding it as a name suggestion in the picture file namesuggestion list. The picture archive of block 207 illustrates thatmemory unit or that part of a memory unit where the picture files of thedevice are saved. The arrangement also includes a user interface forprocessing the picture archive. In addition, the arrangement comprisesmeans for comparing the file recording times in order to find the nameof the previous picture file from the picture archive.

According to an embodiment, the arrangement also comprises means forsearching data from the operation profile 208 and from settings 209, aswell as means for creating a name suggestion on the basis of foundinformation, as well as means for adding the name suggestion in thepicture file name suggestion list. The profile 208 means a file thatincludes user-specific information for defining a user-specificoperation environment. The definitions of the profile 208 are related tosound choices and their volumes, for instance. As for the settings 209,they comprise general call settings, language and network selection aswell as a possible greeting text that is displayed on the screen 203when the device is switched on. Among these, there can be looked up agiven, predetermined piece of information, or information associated tothe picture on given grounds, which information is then used forcreating a name suggestion to be added in the picture file namesuggestion list.

In the embodiment of FIG. 2, there also is illustrated the imagerecognition block 210. According to an embodiment of the invention, thearrangement comprises image recognition means 210 for processing thepicture to be saved and for finding in the picture the features thatshould be recognized, as well as means for generating a name suggestionaccording to the features recognized in the picture. The pictureavailable in the device can be processed by the means and algorithmsprovided in the image recognition block 210 in order to find in thepicture such targets or elements that should be recognized. By means ofthe image recognition technique, there is obtained information as forthe contents of the picture to be named, and from these targetsassociated to the picture contents, there are obtained extremely goodand descriptive file name suggestions to be added in the name suggestionlist compiled according to the invention. By using the image recognitionmeans illustrated in block 210, in the picture that is taken, there issearched a familiar or known pattern or target for instance according toa pattern recognition algorithm. For example a familiar place can berecognized in the picture. On the basis of the recognized targets, thepicture can for instance be further classified in a group of earlierpictures, whereafter the picture file name suggestion to be added in thename suggestion list can be a group-specific name suggestion or thefirst part of it.

FIG. 2 illustrates a phone book 211; the data contained in said phonebook can also be utilized when creating name suggestions according toembodiments of the invention. From the point of view of the invention, afeasible name suggestion can be generated for example of the state datasaved in a dynamic phone book 211. The user can record in the dynamicphone book 211 a piece of state information, for instance “I am at ameeting”. In addition, the user may grant given other users permissionto request this piece of state information. The state information mayinclude data both in text and image form. According to an embodiment ofthe invention, the image data of the state information can be furtherprocessed by image recognition technique in order to generate namesuggestions.

The embodiment of FIG. 2 includes means for enquiring the location dataof the mobile station and for creating a picture file name suggestion onthe basis of the received location data. For positioning, FIG. 2includes a GPS (global positioning system) block 212, through which themobile station can receive location data produced by the globalpositioning technique, which data typically comprises the currentposition coordinates of the mobile station. In addition, the mobilestation is provided with means for processing the received locationdata. For example, there can be available a map application, by means ofwhich the location coordinates can be transformed into address data orother verbal location data on the basis of the received locationcoordinates.

FIG. 3 illustrates a method according to an embodiment of the inventionfor creating a name suggestion list. In step 301, in the mobile stationthere is looked up the date and time information that is associated tothe moment of shooting, said data is turned into a name suggestion, andsaid name suggestion is added in the picture file name suggestion list.In the mobile station, there is looked up the date and time informationrelating to the moment of shooting, and on the basis of these, numericalname suggestions, such as date and time, or verbal name suggestions,such as morning, night, summer, winter, can be generated in the namesuggestion list.

According to an embodiment, in the mobile station there is looked up acalendar event that is at a given accuracy associated to the moment ofshooting, and in case a suitable calendar event is found, said calendarevent is added as a name suggestion in the picture file name suggestionlist. In step 302, the calendar events are surveyed, and theirsuitability as name suggestions for picture files is studied, forinstance by comparing their point of time with the device's shootingtime information found in step 301. In case there are found calendarevents or notices associated to the same point of time, at a givenaccuracy, they are added in the name suggestion list. The calendar mayinclude a notice for instance of an event or anniversary, such asfootball training, an outdoors concert or a birthday party, which aregenerally good and descriptive suggestions to the name suggestion list.

In step 303, in the mobile station there is looked up the file name ofthe previously saved picture file, and it is added as a name suggestionin the name suggestion list of the picture file to be saved. Thepreviously saved picture file is looked up in the picture file archiveor a corresponding location, where the pictures are saved. In this stepit is also possible to search other information associated to thepreviously saved picture, particularly if only a short period of timehas lapsed after recording the previous picture file. If the periodbetween the two last pictures is shorter than a given limit, the newname suggestion can have the same first part as the previous picture.However, there must be a distinguishing feature between the file namesin order to be able to identify them as separate files. According to anembodiment it can be defined that the default name set for twosuccessive pictures taken within a short period of time can be one andthe same name suggestion. Then the file names can be somehowdistinguished, for instance by means of a name suggestion to be added atthe end of the name. According to an embodiment, the feature used fordistinguishing the picture files is the point of shooting time looked upin the device clock, because two separate pictures cannot have exactlyidentical shooting times.

In step 304, in the user-specific operational profile data of thedevice, there are looked up possible name suggestions for the picturefile. In step 305, from the device settings and the current mode, thereare looked up possible suggestions to the name suggestion list Accordingto an advantageous embodiment, from the mobile station profile andsettings, there is looked up information that is associated to thepicture on certain grounds, such as the name of the chosen ringing tone,the name of the logo, the welcome note, the name of the user profile oranother existing piece of information, which is then added as a namesuggestion in the picture file name suggestion list. According to anembodiment, from the dynamic phone book of the mobile station, there islooked up the state information set by the user, and said stateinformation is set as a name suggestion for the picture file. The stateinformation is the current state information set by the user, which istypically a piece of information that can be looked up by certainpersons defined by the user. The state information can for exampleexpress that the user is abroad, in which case the person who looked upthe information in the mobile station may for instance arrange tocontact the user at a more suitable moment, or at least he is aware ofthe possible time difference between his place of stay and that of theuser who is abroad. The state information may contain text that can beused as a name suggestion as such or after editing. In addition, thestate information may contain picture information which can be editedinto a name suggestion for example by means of image recognitiontechnique.

According to an embodiment, the picture to be saved is processed by amobile station image recognition algorithm in order to generate picturefile name suggestions on the basis of features recognized in thepicture, and the generated name suggestion is added in the picture filename suggestion list. In step 306, the image recognition algorithm isrun, and certain features are looked up in the picture to be saved. Bymeans of image recognition technique, it is possible to observe forinstance the brightness of the picture, the patterns, persons, targets,places, environments etc. presented in the picture. From these, therecan be generated name suggestions, or they can be for instance comparedwith the corresponding feature of the previous picture, and the namesuggestion can be generated on the basis of this comparison, so that thecommon features are added in the name suggestion list. By using imagerecognition technique, the pictures can also be arranged in groupsalready at the recording step, so that the name suggestions generated onthe basis of given features—which features and suggestions were alreadyrepresented in an earlier picture or picture group—are priorized to bethe most important and are placed highest in the name suggestion list,so that in the generated name suggestion list, the name suggestions arein an order of importance, and the one that is priorized as the best isfirst in the list. For instance when generating name suggestions, on thebasis of the brightness of the picture it can be assumed that the timeof shooting is night. In case said point of time is night also accordingto the mobile station clock, said two hints obtained from two differentlocations support each other, so that said hint constitutes a reliableindication of the shooting time. According to an embodiment, the createdstrong hint is added as a name suggestion, typically at the top end ofthe name suggestion list.

The name suggestion lists of pictures that contain same featureslikewise contain same name suggestions and even in the same order, incase the same priority rules have been applied. The pictures can begrouped on the basis of the default names suggested for the picturefiles, so that the default names of picture files that resemble eachother and contain same features include the same name suggestions foundin image recognition.

In step 307, there is looked up the current location information of themobile station, which information is produced for example by means ofthe GPS positioning technique. The coordinate information obtained fromGPS positioning can, for example by means of a map application used inthe Internet, be transformed for instance into verbal address data or toa place, building, land or town recognized on the basis of the locationcoordinates. Of these, a name suggestion according to an embodiment ofthe invention can be created. Some well-known targets, for instance theStatue of Liberty, can be recognized both in the picture by using animage recognition algorithm, as well as on the basis of the producedlocation data of the mobile station.

According to an embodiment, in the mobile station there is looked up aname suggestion defined by the user, and the found name suggestiondefined by the user is set as a name suggestion in the picture file namesuggestion list. In step 308, there are looked up in the memory the namesuggestions fed in by the user. The user may feed and record the mostgenerally used names in his device. These are always included in thename suggestion list to be created. In the embodiment of FIG. 3, theseare printed separately and last, but naturally the user's own namesuggestions can be added for instance as a part of a user-specificprofile, in which case corresponding information in this embodimentwould be looked up in step 304. In connection with the description ofFIG. 3, there are given examples of the information to be compiled inthe name suggestion list. Obviously the name suggestion list can becompiled further or in a way different from the above description, bymeans of any piece of information already existing or available for thedevice, or by means of information produced on the basis of the picture.

According to an embodiment, the name suggestions in the generatedpicture file name suggestion list are priorized according to certainpredetermined priority rules, the name suggestions are set in order sothat the one with the highest priority is placed highest in the list,and the first name suggestion in the name suggestion list is set as thedefault name for the picture file in the user interface. In theembodiment of FIG. 3, the generated name suggestions are priorized, i.e.set in an order of priority according to given priority rules in step309. The priority rules can be defined In several ways that areapplicable in any given situation. For instance it can be defined thatthe name suggestions are looked up in a given order of importance, sothat they can be added in the name suggestion list in the same order asthey will be looked up, and the separate priorizing step 309 is left outas unnecessary. Secondly, always when a new name suggestion is found, itcan be compared with the ones already existing in the list, and a placefor it can be found in the list. Typically the most important namesuggestion that is classified as the most appropriate is placed first inthe list. The suggestions can be arranged in an order or priority, sothat the order is defined according to from where or in which step thename suggestions are looked up. According to another embodiment, theorder is affected by which suggestions are identical with those of thepreviously saved picture. This is typically associated to a time limit,so that the information of the previous picture is valid for instanceonly if the date is the same, or for example so that when the previouspicture becomes a week old, it does not anymore have significance whennaming a new picture. According to an embodiment, it can be defined thata possibly found calendar event that suits the point of time always isthe best hint. According to another embodiment, all hints are comparedwith name suggestions generated by image recognition, and the mostappropriate among these is chosen according to the priority rules.Moreover, the priority rules may define that for example verbal hintsalways come before numeric hints, or that five-letter name suggestionsare priorized on a higher level than for instance two- or eight-lettername suggestions. According to one priority rule, the name suggestionsselected for the highest level are those that best resemble the searchedinput fed in by the user. The priority rules may define that in case twoseparate searches result in the same or nearly the same name suggestion,it is raised higher in the order of priority than where the namesuggestion as such would qualify. Typically the default names favornames that contain a known word or term, because a verbal name alwaysgives a hint or assumption as for the contents of the named file, whichis essential when processing the files later.

After the name suggestions are priorized in step 309, from among themthere is chosen the most suitable default name with the highest priorityfor the picture file in step 310. In this embodiment, the name that wasclassified as the best suggestion in step 309 is now set as the defaultname for the picture file. In step 311, the generated name suggestionsare displayed to the user on the display of the user interface. On thebasis of the displayed name suggestions, the user may replace thesuggested default name with a completely different name, or he may editthe suggested name. The picture file name can be chosen among the foundname suggestions by pointing one or several of them, or by editing thename. The name can be compiled to contain several parts, so that forinstance after the default name “duck” generated on the basis of imagerecognition, there is added the season created on the basis of the dateinformation by selecting it from the user interface menu, where the namesuggestions are presented. Now the adopted name is for instance“duck-winter”, in which case the first part of the name describes thecontents of the picture to be saved, and the last part associates thepicture to the moment of shooting. From the created file name, there canalso be drawn the conclusion that the saved picture represents awinter-coated duck bird. According to an embodiment, in between theparts of file name suggestions compiled of several parts, there is addeda separator, such as the hyphen (-) used in the example above. After thefile name, there is generally added a qualifier automatically in theuser interface.

When the desired picture file name is chosen, the mobile station checksthat a corresponding file name is not already saved in the mobilestation. In case a completely identical file name is found, according toan embodiment the mobile station informs the user to that effect. Inthis connection, the user may be asked to change the name, if he doesnot wish to save the picture to be recorded in the file with the samename that was saved earlier, in which case the contents of the earlierpicture file are lost. According to another embodiment, the mobilestation adds in the name suggestion for instance a serial number, a timeparameter or the name suggestion located next in the name suggestionlist, by means of which the file name can be distinguished from thepreceding name. Typically the picture to be saved is not written in thealready existing picture file, but the user is informed of thesituation, and there is possibly suggested a change in the picture filename chosen by the user in order to identify said file.

One embodiment of the invention can be immediately applied when thepicture to be saved is taken by the mobile station camera. Thereafterthere is, according to an embodiment, created a name suggestion list,and a file name is automatically suggested for the picture according tothe name suggestion that has the highest priority. The name suggestionlist is presented in a user interface according to an embodiment, andthe user may pick the desired suggestion/suggestions or edit the namemanually, for instance through the keypad. According to anotherembodiment, the name suggestion list according to the invention iscreated already before shooting the picture to be saved by the mobilestation camera. The user may edit the picture file name to be created ashe wishes, by using the name suggestions or without them. The namesuggestion list is compiled on the basis of information that isavailable, such as the name suggestions defined by the user, the name ofthe previously saved picture file, the setting and profile data saved inthe device. The created picture file name is typically used as a prefixfor the pictures to be saved next. According to a third embodiment,there is named an earlier recorded picture file that is already saved inthe memory of the mobile station. For the picture file saved in thememory, there is created a name suggestion list according to anembodiment of the invention. All data regarding the moment of shootingthe picture file saved in the memory is not necessarily availableanymore, but in this embodiment, it is possible to utilize the availableinformation that can be produced or looked up by means of the existingpicture file. For instance, a calendar note that is possiblysimultaneous with the earlier moment of shooting already is probablyunavailable, but the picture file can be processed by image recognitionmeans, in which case feasible name suggestions for the name suggestionlist to be created are generally obtained on the basis of the picturefile contents. Also in this embodiment, name suggestions and means forchanging the default names are offered for the user in the userinterface display.

In the above specification, we have by way of example described variousways for generating name suggestions according to embodiments of theinvention on the basis of the information available for a mobilestation. The described embodiments and the examples contained therein donot, however, restrict the scope of the invention.
